I don't know. It's not on the list of supported scanners. Can you or someone test that model to see if it works.
Set the scanner type to BCD536HP and see if the serial port & Wi-Fi works then put it in Mass Storage mode and see if the FL can be read and written.
Unless you know someone who has one of those model scanners you can try your copy of the software on then I think you might be out of luck unless there's someone on here who has done it.
The SD card for a UBC536PT scanner have it's root file folder named to ubcdx36 instead of the normal BCDx36HP, so if Proscan doesn't support that scanner it can't read the files.
